不能访问用TouchJSON创建的字典

Question

我正在尝试使用TouchJSON，下面是我所做的测试:

NSString *jsonString = @"{"firtname": "Matthieu","lastname": "Ravey","age": 22}";
NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSError *error = nil;
NSDictionary *dictionary = [[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error];
NSString *firstname = [dictionary objectForKey:@"firstname"];
NSLog(@"%@", firstname);

但是它记录的是null而不是Matthieu，我错过了什么?

谢谢

Answer 1

在你的json字符串- NSString *jsonString = @"{"firtname": "Matthieu","lastname": "Ravey","age": 22}";它说firtstring。

尝试使用相同的键访问此字典!

所以变化是-

NSString *firstname = [dictionary objectForKey:@"firtname"];
